Answer:

D

Step-by-step explanation:

y = -1/2x + 18.5

check it by inserting the day number and comparing with the chart

y = -1/2(2) + 18.5

y = -2/2 + 18.5

y = -1 + 18.5

y = 17.5

Simplify 4n5 + 3.5n5 + (-2.1n5).<br><br> 4.4 n5<br> 5.4 n5<br> 20 n5<br> 6.4 n5
ella [17]

Answer:

4 {n}^{5}  + 3.5 {n}^{5}  + ( - 2.1 {n}^{5} )

first create a bracket:

= ( {4n}^{5}  + 3.5 {n}^{5} ) + ( - 2.1 {n}^{5} )

then solve the first bracket:

=  {7.5 {n}^{5} } + ( - 2.1 {n}^{5} )

then open the remaining bracket:

=  {7.5n}^{5}  -  {2.1n}^{5}

carryout the subtraction operation:

= (7.5 - 2.1) {n}^{5}  \\ { \boxed{ =  {5.4n}^{5} }}

Elkton Heights 16 miles each day on a 12 day hiking trip Lola height 14 miles each day on her 16 day hiking trip and all how man
babunello [35]

Answer:

32

Step-by-step explanation:

To compare how much more Lola hiked we need the miles that each one hiked.

Elton hiked 16 miles each day for 12 days, the total amount of miles he hiked we can found by multiplying 16 by 12:

16miles(12) = 192 miles

Lola hiked 14 miles each day but for 16 days, so the total amount of miles she hiked can be found by multiplying 14 by 16:

14miles(16days) = 224

The difference of miles we found by subtracting 192 (elton's miles) from 224 (lola's miles)

224 - 192 = 32
